To all whom it may'comcr-n:

' means ior delivering the article on to a wrapper and Be it known that I, LINGAN'C. WING, a citizen of the United States, residing in New York city, in the county of New York and State of New York, have invented certain new and usei'ul Improvements in WrappingM-achines, of which the following is a specification.

This invention has reference to an organized ma- I chine for automatically inclosing in a wrapper of flexious forms, or other articles, similar to the wrapping of such articles as would be performedby the human hands. I Y

The objects of the invention comprehend improved folding the same around the cake, and bending up the end portions against the article; means for thereupon delivering a labeling strip to, and wrapping the same around the-article and securing the strip by suitable adhesive.

A further object is to provide in a wrapping mechanism suitable plungers or the like engaging members that are broughtto engage the article by a resilient means, in order to compensate for inequalities in the size of the article and prevent breaking thereof.

A further object is to-provide in the process of turning down various portions of the end folds, means for holding each turned portion until the next succeeding portion is turned down and secures the former one in position. I

A further object is to provide means for folding a strip, preferably gummed, around the wrapped article, whereby the strip will be wrapped around the article with its gunnned extremities engaging, and thereupon retained in such position until the article is advanced to pressing means to suitably press such ends together upon the article in secure them in such position.

With these objects in view, and others, inyinven tion comprehends the novel ponstruction and arrangenient of parts and combinationsthereof as will be hereinaiter set forth, and then particularly pointed out in the claims. I

A. suitable fame projects rearward from the main frame of the mat-blue and between its parallel bars 3, 3.. are journaled a number of rollers or shafts. one of them, 4, serving to roi'atably supporta roll of paper not shown. The paper and foil are f ed intermittently on to the table of the machine by means of a pair oi rolls (3 and 7, the former having its shaft 8 journaled in suitahle frame 9 and mtated from a gear 10 fast to the roll that meshes with a gear 11 fast on the roll 7, whereby the latter is driven from the other roll. The mechanism shown [or driving the roll 6 from the main shaft 12 of the mittlllllt comprises a rack arm 13, pivoted at its lower end on an extension 14 of the frame 9, Whieh arm carries a roller 15, held in engagement with a cam (wk it; hya coil spring 17 suitably r-onneeted with the ra no of the machine. This arm 1.3 serves to roeipro- (fill-0 a rark bar 18 to which it is pivotally connected, which bar slides in a guideway in the frame 9. The

This stripper plate 290 is also provided with fingers .29 extending forward over the webs of paper and foil in dose proximily to a (titling knife Ill, by which the stripsof paper are severed after being: posilioued on the table.

The eutting knife 31 is caused to art at the end of ear-h. intermittent motion of the feed rollers, that feeds the web 'on the wrapping means on the table. This cutting knife, as best shown in Fig. 31,- is pivoted to a suitable upright from the frame at 32, and has pivoted at; one end a bar 33. A roller 34 married at the lower end of this bar is held against the surfaee of a (am 35 fast on the main shaft 12 by a spring 36 ht't'lllltl between the knife and the framework. The rise in the (am being abrupt (arises the knife to q uiekly doseend, and the fall in the (am permilslhe knife to be drawn up by the spring to its normal upper position. The knife blade ceperat-es with a knife plate 37 suitably mounted on the table of the machine. A plate 38 extends rearward from the table against the lower feed roll 6, serving to strip the sheet or sheets therefrom an fed through, The knife is curved as shown to present a. (onstant angle with the plate 37. 1

Referring now particularly to Figs. 3 and 9 to 19, the table or bed plate of the machine is supported upon suitable legs 40 at- "at-h end. At one end of the mar-hine a magazine or hopper 41 is suitably supported from an upper plate 42; raised above the table 3!]. The artirles, which may 'he Fakes 43, are fed into the hopper, and the lowermost onerests on a stationary plate 44 suitably support-ml from plate 42. The table is'provicled with an opening 45, in whit-h operate-4 a platform 46, that is normally supported above the table by resilient or vieldable means,- and depressed from nut-1i position by positively acting moans actuated from the main shaft 12. in the present instant-e. the platform has a shank 47 guided in a box 48, sm-ured to the lower fat-(- of the table, and 11. (oil spring ll) rests on the lower portion of the bokand normally retains the platform elevated, as indii-ziti-d in Fig. ,I(). (in the shall. 12 is a disk 50 having a (am flange 51 that is vngaged by a roller 52 pivoted on the shank -17 of the platform. The spring lorring the plnlform upward holds the roller in engagement with the innei faro of the flange on the ram, and during a. revolution of the (-am the platform is (ll'lll'thSt'tl and then oloratud to its former position, as will be seen by inspoet ion of Fig. 21. it will l)'(' obvious from this eonslrui'tion that the raising of the platform will permit it to yield in ruse it i-n- ,{i'lgtliitll irregular al'tiele, and not break the same, which would result if the platform were positively raised and not permitted to yield. 4

Diri-itly above the platform is suitably mounted a plunger 53 sliilably supported and :u-l-uutod to ('ooperate with the platform-aftor a wrapper and artivle has been delivered on to the plalform. in the devit'o hhowii tho lnblo in provided with a framework 54 varrying a guide-hloi-k. 5-3, in \vhivh thiphingor shank 51S i'i-uipi'oi'uti's. 'lhis plunger is also moi od to one position by a, yield-able nn-ansand actuated ib thoopposite and extendinginto. the slot'70 at the other side.

direction by positively acting means. 54 is suithbly mounted a rock shaft 57, on which isse- .curedan arm 58, (see Figs. 38 and 39), the forward end of the, arm being pivotally connected with the shank 56 by slidable connection. A lever 60 has one end pivoted below the table, and its other end pivotally connected with a link 61, the other end of the link being pivoted to the rear end of the link 59 fast on the shaft 57.. A coil spring 62 has one end fast to the lower end of the link 61, and its other end is secured toastationary member such as a pin 63 projecting rearward from the fraln'io 54. The spring tends to move the link upward and thereby retain the plunger in its lowermost position. This motion is counteracted by means of a roller 64 pivoted on the lever (30, and hold in engagement with the inner face of a flanged cam 65 fast on the main shaft 12. Dining onc revolution of the mainshaft the cam will pcrniit the lever 60 to be elevated by the spring, causing the depression of the plunger 53. This cam 65 is shown separately in Fig. 20, from which it will be scen -that during about two thirds of the revolu tion the platfornii remains elevated, then it is depressed by a rise in the cam, and then a dwell in the cam holds the plunger depressed for a short time; after which it is permitted to rise to its normal upper position. The operation of the platform 46 is similarly controlled. The cam 50 for about half of its revolution holds the platform depressed, then a quick rise leads to a comparatively long dwell in the cam, during which time the platform will remain elevated; and then a fall in the cam returns the platform to its depressed position, as will be apparent from inspection of Fig. 21. The normal upper position of the platform is slightly below the top of the plate 44- supporting the lower cake in the magazine; but is substantially flush with the top of the bridge plate (36, that is supported above the table, and removed therefrom for a distance slightly greater than that of the article to be wrapped. 'This bridge plate is shown as supported to yield upward in order to allow for any increased thickness in the article and prevent breakage of thecake. The frame 54 carries a two-armed bracket 67, from each of which arms project pins 68 extending through suitable apertures in the bridge plate. A coil spring 69 surrounds each pin and has its ends secured respectively to the arm and bridge plate; thereby permitting slight elevation of the bridge plate. I

The plate 44 is provided with a slot 70 extending inward from its edge adjacent the platform; which slot lies substantially in the plane of the top of the bridge plate 66. The web or webs fed through the feeding rolls (land 7 after passing the lower knife edge 37, advance on to the platform that at this stage is in its elevated position the cdges of the web beyond the platform lying on.the bridge plate at one side, As soon as this intermittent motion of the feed rollers ceases, the lower cake, is advanced on to the wrapper portion immediately above the platform, byfa main food ram, in the present instance a plate 71 reciprocatlcd' in suitable guide strips 72, best shown in Fig. 2. This feed .ram isreciproatod by a drum 73 having a cam slot 7 therein that is engaged by a roller ,75, pivoted 0117a pin 76 projecting downward from the ram 71v This drum-is also shown in- Figs. 23 and On the frame 29. This ram is normally retained in the position on the web, which will tend to retain the severed wrapper portion in such position. The next operation of the machine will cause the descent of the main plunger 53 on top of the cam on the plunger. This plunger is provided with flaring extensions 77- at two opposite portions, which serve to properly position the cake on the platform. When the plunger has dcscended far enough to engage the cake it has not made its full lowering movement, but its cam permits it to descend further. But as sdon as the plunter reaches this engaging position, the platform begins to be lowered by the cam, and the two descend together until they reach the position indicated in Fig. 11, when the platform will be level with the table. From Figs. 10 and 11 it will be seen that the lowering of the platform and plunger from the position of Fig. 10 will cause the wrapper at each side of the plunger to en.-;

Wrapper will be'pressed snuglyagainst the side of the plate; but where a resilient wrapper, such as stiff or pa'ratlincd paper is employed, this will tend to buckle or curve outward during such folding. To obviate this effect I provide a'spring clip 78 pivoted at a chamfered portion on the lower face of the bridge plate adjacent the platform, see Fig. 18. This clip. is normally retained by the spring 7 81in engagement with the platform, as shown in Fig 11. The portion of the clip contacting with the platform, as the plunger moves the article downward, will first engage the paper adjacent the lower edge of the wrapper and follow the paper upward, tightly pressing it against this side of the wrapper. When at a further stage the article is advanced under, the bridge plate by suitable means the spring clip will'fold upward under the chamfcred portion of thobridgc plate, as indicated in-Fig. 13. 1

The succeeding operation after folding two side edges up, as shown in Fig. 1] is to fold the upturned edge, seen to the right hand of those figures, downward on top of the cake; and this is accomplished by means of a folding ram slide 79. This slide carried a pin 80 having a roller 81 engaging the walls of a cam slot 82 in a drum 83. This ram slide will be advanced from its normal position indicated in Fig. 11 to that shown in Fig. But just before the operation of this rain the plunger 53 is moved upwards by its cam. This folding rain is not at onccretracted, but is retained in such position by reason of the dwoll'in the cam slot, as indicated in Figs. 24 and 2 8. And during this dwell, the cake is advanced under the bridge plate by a clearing l'iI-lIiSllLlO S4 operated by a roller 85 on a pin '86 engaging a can] slot 87 in a drum 88 me on the shaft 12.

l 7 I i l This advance of the cake under the bridge will cause the upward extending portion of the wrapper adjacent the bridg plate to engage the latter, and also the spring slip and be folded downbu top of the cake,a1 1d the or her folded portion. as will be obvious. bycompnrison of Fig. 12 'aud lit. The clearing ram 81 has a thin strip 64 I. overhanging its engaging end that passes on top of ihe cal-1c and provonts its being pushed up by the rain: that might be caused by the inclined edge oi the cake. The folding ram slide 79 is now returned to its lor'uu-r phnion. having served to retain the portion oi the wrapper that is folded. down until the cake passes under the bridge plate, and has the other portion folded down on top of said portion. Thus itwiltbe seen that upon a, portion being folded down it its hold in such positionuntil subsequently engaged by aliuperposcd flap or portion of the machine, thoreby preventing the fold swinging away from the article. The folding' down of this second upturned portionis further assisted by means of a stop plate 89 suitably connected with the framework of the machine and extending down to Within a short; distance of: the

' extremity of the bridge plate adjacent the platform.

When the wrapper is engaged by the descending plunger 53 as indicated in Figs. and ll, the extreme ity oil the bridgefnlute 66 will cause the adjacent end or projecting portion of the Wrapper to extend onward,

as indicated in Fig. 11. And upon the mo'vomentnf the rarn'slide 84 to advance the article froni the positionof Fig; 12, t'o'that; shown in Fig. 13, during which opera tion, the plunger 53 ascends, the wrapper being carried by the article, willbocngaged by the end of the bridge plate which would force the wrapper against the adja cent edge of the plunger, and the upward inotion of the latter would tend to injure the wrappt a This in prcvented by the presence of the stationary suspended (in- [lecting plate 85), whichengogcs the upturned portion of the wrapper as shown in Figs. 1 J and 12 and holds it away from the upwardly moving plunger. The latter movemont oi the cake by the clearing rain brought it to a. position on the plunger where itcan be engaged by a creasing nun 90, whose shank 91' slides in a suitable guide-block 92 supported from the flame li-l. 'lhis illunger is operated by means similar to that operating the other plunger 53, comprising air-arm llfl [not on rock shall 931 lowing one end pivotcd to the shank fill of the plunger. The shaft 93 has an arm B32, roiinccteil byd link Si l with the free end of the lever flopivomd boncalh theluhle at the front. A roller EH3 on the lover S is held in engagement with the wall of ti tlsrngn lLllU $.17 last on the shaft; 12. at, means of a. rvtractilo a ring Elli lust bot 'Wttll the lower end of thcliul; ll-lund'a. pin til extending; rcarwurdlroul the frame Fri. By this towns the plunger U0 is positively elevated to its uppor position, and lirwercd by the spriugwvhcurio permitted by the cam. This plunger is provided with plates llltlat each side having projecting .llungc parts the plates extending downward a sullicicnt disliltn'c to override the bridge pinto llli. and lt'i ongagc the portion ol' the wrapper projecting beyond the cake at the top on each ol twosidcs, as indii'otc'd in Fig. H. As soon as Llu cake is brought; tothc position indicated in Fig. 13, this (i-casing plungcr iu brought do\\"u\\'-.u'd and then rotrut-ted.innucdiaicly: causing cud l'old. as houn in Fig. 3 1. As soon as the creasing plunger rises u sidc wiper arm is advanced to engage the side portion at each cud ol the cake and loid it down on top of the top t ld just. produced. This is tu'r'oluplislu-d by inc-ans ol' a. member comprising,- two parallcl strips l ll slidublc on the table and guided by the said blocks; connected at their rear end by it transverse piece 102. t A pill 103 extends downwirrd from the hitter transverse piece and carries a roller HM engaging the walls of a groove 105 in the (inn drum IDS-lost on the shaft; 12. lmniediatcly upon the creasing plunger beinginov'ed upward from the cake, these side wipcrn advance to fold down at "each end a side [old on top of thel op fold just produced, as indicated in Fig. 35. The next operation of the machine causcs'ti still further advance of the clearing ram 84 to advance the article a short distance, and the mam d rum operating the eide wipers is arranged to still further advance a short distance to hold the side fold down on the cake. second advance of the clean ing mm is effected by a second rise in its "cam slot, as indicated in Fig. 25, and then the clearing mm returns to its former position; both of such means being et'l'ccted during one cycle, that is, during one revolution of the main drii'ing shaft. But during. this-- moons of ast r tionary folding block 107 arranged on each side ofthe table in the path of movement of the article, as indicated in Figs. 15 to 17. This will cause a second end fold down on top of the top told as indicated in 36. This will complete one cycle of operations by reason of a complete revolution of the main shaft, and the several orts will be returned totheir for ner posh tion, it not already returned, in order to repeat the operation at the next revolution of the main shaft. The article with three of the our end folds being eifectcd as showii in Fig. 36 is left in the position indi- "ated in Fig. 1.5, and upon-the linat movement of the clcaringrnm in the next cycle the article first 'ltlpptj'll will be advanced or o. fmction of its width, and the second movement of the clearing nun advancing the nrticle being'wrappcd' will still further advance the that article, having moved it during those two moremerits of the clearing rain for an aggregate distance equal to the width of the article. As soon as the first article is ad rant-c lby the next article. it passes from the folding" lllfiCliS lOT to iolding blot-ks lOB ildjaccut to lhc latter. whereby the linol bottom fold is folded up on to the end oi lll(1ll'll('lt\ll indicated in Figuil't', thereby, completing the folding or lllL article at both ends.

The tour mun drums too, T3, ii and HS. mounted on the main sluil'l l2. as shown in Fig.2. lJ/uro shown st-puruit-ly in l ig s. 21%. 24.25 und 115. are also lli \\'ll din-unin- !l\:\ll(;\ll iufhigi JT and 2H, 2H and Ill] rcspcci1\cl 4 ln llll'. 'tl1!:-l ligurcs the periphery of cat-h of such cum lift) drums is indicated as laid out in a plane and snowing the relative positions of the operating part of each cam groove. The transverse broken lines 1 to 9 indicate the relative active positions of these grooves. The dam drum 73 is the first one brought into action at the begining of the wrapping operation, which serves to ad- Vance the main feeding ram 71 to advance the cake onto theraised plunger. The bottom portion of this same is true of the cam drum 88, which opcrates the,

clearing min. In regard to the other cam 106 operating the side wiper, during a part of the movement of the rotation of this drum the side wiper will be returning to its inactive position, and from the preceding operation, and for therest of this period this cam does not actuate the side wiper. From the line 1 theroller will travel back to line 5 to its former position by a continuation of the rotation of the drum, and thence the roller will remain inactive during the continuation of one revolution, and need not be further considered.

' ,When the drums'have revolved .until the portion of 'IineZ until a position indicated by the transverse line each indicated by the broken line 2 is uppermost, and the grooves engage their-respective cams at such positions, it will be seen that the folding ram operated by the groove in the cam-83 will now begin to travel by reason of the rise or'slant-inthe groove, from this 4. During this stage thefolding ram operates to fold one side of the wrapper down on the article, as pre-' vlou sly explained. But this folding operation is completed before the rollertravlithe limit of this incline and at a portion of it indicated by broken line 3 the groove in the cam 88 begins to slant, thereby advancing the clearing ram. The effect of this is to cause the clearing ram to advance the article and the folding 31am to simultaneously advance for a short distance in order to hold the folded portion of the wrapper down on the article. It will be further observed from Fig.

. that the side wiper begins to advance at the position of the transverse line 3, but it does not come into engagement with the article until a later stage. From the position of the line {the folding ram groove has a circumferential direction, thereby retaining the ram in its advanced position and holding the folded portion of the wrapper down until the position of line 7, at which. stage the article will have been advanced beyond engagement with this ram. 1t thereupon retums to its normal position and is not again operated during this revolution. vanced from a position of line 3totl1at of line 6, when it will have advanced the article under the bridge plate to a certain position for engagement with the creasing plungerfthat is'thereupon caused to descend by its spring and controlling camh From the position of line to that of line 7 the creasing plunger is quickly The gclearing ram is sci-- brought down and retracted, and thereupon at the lat-- ter part of this period the side wiper cam that has been advancing from position of line 3, engages the side of the article to fold down, which is accomplished at the period represented by line ,7. Thereupon the sidewiper is still further advanced to the position of line 8;

but from the position of line 7 the clearing ram is advanced simultaneously with the side wiper. The effect of the latter is that the side wiper holds its resultant fold down on the article while the clearing rain advances the article, causing the latter to engage the stationary block 107, and fold down the opposite side portion. The clearing ra'in continues to advance to the position of line 9, completing this folding down by L the stationary blocks, whereupon the clearing ram returns to its former position during the remainder of the cycle. From the position of lines the side wiper begins to return to its former" position; which, however, is not accomplished until the beginning ofthe next cycle, as indicated in Fig. 30, and previously referrcd to. This folding operation may be donowith a single sheet or two or more sheets superposed, and .is I

shown as'accomplished with a sheet of parafiined'paper placed on top of a sheet of tin foil, which sheets when severed act as a single sheet and are folded around the article as a single sheet would be, the air foil being on the outside.

i In order to retain the overlapping folds at th and-the overlapping portion extending a'cross'oneiace, in such position; it is customary to provide a strip or label that is wrapped around the article with the ends overlapping and suitably secured, preferably by gum. This strip may containa suitable inscription or design designating the contents and manufacturer. In the present machine the cakes are advanced along under e end,

forming a continuation of the folding strips 108, to .a

mechanism that feeds a strip under the article, places adhesive on one portion of each strip, wraps the striparound the article with the guinrned end overlapped by the opposite end, and thereupon presses these lapped" ends together to insure their adhesion.

The, table 39 is provided'with a recessed portion in which rests normally a platform 145. The platform is elevated to a position substantiallylevel with the table by a suitable cam on the main shaft 12, andis permitted to lower by a fall in this cam, assisted by expansion of springs. In Figs. 48', 49, and 50, the platformis shown as having two posts 146,:146, secured thereto, and extending downward through apertures in a bridge piece 155 that is secured to posts 152. The lower endsof the posts 146 are, rigidly connected by a bridge piece 148, which latter rides on the periphery of a cam 149.fast on theshait 12. Springs 150 150, ai-

ranged on the posts 146 befieen the table and collars 151, 151, serve to move the posts and platform downward and hold the press piece 148 against the foam 149. In suitable openings in the table adjacent each of the platform are arranged vertical movablemembers for the purpose or bending upward a strip of paper that has beeninsertedbenesth a cake. Each member is shown {is composed of two parts,"a post 152, and a block 153 p "'oted at the. upper end 5f eajchfposflthe.

has: sliding in openings 154 in the table." Theits 152 are connected at their lower portionif'by a' bridge its free end arranged in alinement with the channel portion ofthe table. The blocks 153 are recessed at their intermediate portion to permit these arms to en-' gage the strip at the top edge of thearticle and thereby fold the strips down on top of the article, as indicated 'in Fig. 50, in close engagement therewith. The strip is such a length that its end portions will overlap, and

the giimmed portion adjacent one end: will now be on the upper side oi the strip, and this end is brought at the properi time, and the latter will simultaneously down first, and. then the'other end folded on top of it in engagement with this gummed portion.

The arms 180 are .pivoted on the tahleat 181, and

theirother extremitiesare slotted, into which extends the ends of upright levers 182, 183, pivoted on the irame oi the machine to swing in a transverse vertical plane. lever 183 carries a roller 185 held'in engagement with a cam -186'-fast on the shaft 12 by a spring 187. iThis cam will serve to' rock the lever 183 operate the lever 1.82 through a connecting link .188;

which levers will operate the armsy180 to fold down 'the end'portions of the strip as above set forth. The

cams 149 and 157 each have a dwell to hold the platform and folding blocks their upper position after thefolding arms have moved inward, and the earn 186 is also provided'fiith a dwell arranged to hold these arms in their inner positionfor-a short time. Suitable means is providedwhereby during such'retention ofthe strip in the folded position, the article is advanced along the table between suitable membersengaging' its top and.bottom portion to thereby press the folded and lapping portions of the strip against the article to insure the proper adhesion of the gummed ends of the strip. In 5ll is shown a set of endless belts 1.99, passing'around suitable rollers 19). carried by the table; the rollers being-idly supported so that the beltsare operated by the advancement of the articles. Three superposedpairs of such belts 19 0 areprovided, the lower ones operating in the plane of the table, and the upper onesa suflicicnt distance removed to snugly engage the'top of the article and secure the strip in position. In the present instance this strip folding mechanism is arranged to cooperate with the wrapping mechanism hereinbeiore set forth for wrapping the articles with paper, and tin foil; As the successive articles are advanced by the one last wrapped through the, advance of the clearing ram, they are moved along in the guideway under the bridge piece 66, and the strip folding mechanism is arranged at the other end of th'e bridge piece, with theplatform in alinement with the path of movement of the articles on the table;

The platform is so positioned on the table relative to this line of advancing articles that one of the two ad-' vancedmovements given to the clearing ram duringeadh revolution of the main-shaft will serve-to move the article at the front of this line of articles on to the raised platform 145, as indicated in Fig. 50. All of the operating cams for the strip folding mechanism on the same main shaft 12, andthereby operated to complete the wrapping of the article by the strip during one revolution, the latter cams operating the strip folding mechanism are so set that the plunger will be in 'its normal upright position ready 'to receive this article. when advanced by the plunger at the end of its that will retain the folded strip in engagement with which will have the effect of advancing this article carrying the folded strip between the belts 190 the article for the length of time required to advance the severalzarticles through the "belts. This first move ment of the clearing ram. will advance the strip-folded article for a portion ofitslength between the belts 190, and thesucceeding article Will be partially advanced on to the platform 145'. But the second advance of the clearing ra n that is effected during one revolution,

will advance the said article in proper position on the.

platform,

and the latter will advance the strip folded article between the belts 190,.ciear of the strip folding mechanism. From this it will be seen that the two advance movements of the clearing ram not-only servesto directly eflect the separate folding operations in the initial wrapping or. enveloping oi the article in paper and foil, but also perform a double function of placing the article in proper position on the strip folding platform, .,and further of advancingthe-article-partly into engagement with the securing belts while still engaged by the strip folding meaps to insure the proper securement of the strip on the.article.

,' .Another means for folding the upturned ends oi the strips down on to the article is shown in Figs. 57 ,to 61,

in which instead of the two armsl80 separate from the folding blocks or members 153, a folding member-is mounted on and carried by each of the folding blocks 'similar to 15 3, pivoted on the-upperends of the posts.

152. These folding blocks 192 have identical channels in their top portions in which slide folding plates 193, that are normally flush with the inner edges of the folding blocks, but can be advanced over' the article or platform and serve to fold down the upright portions onto the article, in the manner above set .One means of operating these sliding plates comprises a pair of arms. 'l 94= 194,.pivoted underneath-the table,

and having at one extremity a slotted portion 195, each .of which latter engages rocking levers 19G vertically 'suppcrted'below the-table. One of theselevers hasa roller 197 on the extension that-is held against a earn 198 on the shaft 12 by a spring 199. This cam and necting strip 200; similar to the means for rocking the levers 180. The other extremities of the lovers 194 have a suitable aperture into which extends-a vertical pin 201, secured to and projecting downwardly throngh slots 211 in blocks 192 from each'ofthe plates 193. By this means the rocking of the le ers 194,will reciprocate .the folding plates 193; and the pins 201 sliding tree in the levers 194 will permit a vertical movement-of th folding blocks 192 without affectingthe relative posi- Ltion'of the folding plates on the blocks. 'After these "blocks have been raised .by theposts 152, as above described, the swinging of the levers 194 will move each of-the folding plates inward and foldgdo'wn the up: turned ends. And the plates will be heldin-thisriospring will serve to ,rock'tlieextension lever, that will simultaneously rock the other lever througha conseo,17c
